Brand new models from 160 to 200 kVA of the high efficiency UPS Multi Sentry

Published by Jason Koffler on 07 February 2015

Riello UPS enlarges its offer adding Multi Sentry MST 160 and 200 on the product portfolio. This product integrates the existing three phase MST range 10-120 kVA to offer a complete large selection of transformer less UPS from 10 to 200 kVA. With 12 different power ratings it satisfies any critical power demand (10, 12, 15, 20, 30, 40, 60, 80, 100, 120, 160, 200)

MST 160-200 enlarge Multi Sentry family therefore it follows the general design structure and the UPS operations approach (same logic, same LCD display navigation menu) Nevertheless, MST 160-200 is at the cutting edge of UPS development taking on board the latest three level inverter technology and intelligent control which grant:


- kW = kVA (output pf =1)
- Very high efficiency (>96%)
- Smart ventilation (saving energy and reduce noise)

kW = kVA

The unitary output power factor grants higher active power availability (+11% compare to UPS with pf 0,9). Furthermore, MST supplies capacitive loads with PF from 1 to 0,9 with no power downgrading applied; therefore it is suitable for any data center application with unitary or capacitive power factor (new server generations which commonly work between unity to 0,95 leading PF). In response to any tender requirement for UPS performances under leading/lagging load applied, MST operates properly whatever is the load power factor range applied.

Very high Efficiency

State-of-the-art three-level NPC inverters grants an overall UPS efficiency greater than 96%. Efficiency overcomes 95% starting from 22% load level guarantee high efficiency regardless the UPS load level; this result in minimizing the losses and therefore the energy cost at any operating load condition.

Smart ventilation

Smart ventilation principle on MST 160-200 manages the number of operating fans and their speed according with room temperature and load level. So doing we preserve fan’s life span and at same time we reduce noise level and overall power consumption for unnecessary UPS ventilation.
